ATOMIZER.

SPEGIFIGATIQN forming part of Letters Patent No. 725,954, dated April21, 1903.

Application filed October 4, 1902. Serial No. 125,911. (No model."

To aZZ whom it may concern: 7

Be it known that I, MOSES GOLDMAN, a citizen of the United States, and aresident of Pittsfield, county of Berkshire, and State of Massachusetts,have invented certain new and useful Improvements in Atomizers, of whichthe following is a specification, reference being bad to theaccompanying drawings, forming a part thereof, in which similar lettersof reference indicate corresponding parts.

My invention relates to improvements in sprinklers or atomizers whereinI provide a bulb or collapsible receptacle for containing liquids, whichis adapted to beheld within and compressed by lever-arms to eject theliquid contained in the receptacle. The said bulb is provided withminute radial perforations through which the liquid is ejected.

The object of my invention is to provide a cheap, effective, andconvenient device which may be used for sprinkling clothes, plants,tobacco, and floors or as a sprayer fordistributingdisinfectingfiuidsformedicinalandsurgical purposes, such ascleansing wounds, the.

A further object is to provide a device of the character described whichis adapted-to be attached to and used in connection with a reservoir andwhich is provided with a de tachable plunger, as and for the purposehereinafter described.

In the drawings, Figure 1 is a general side View of the instrument,shown partly in section. Fig. 2 is a section through the plunger portionof my instrument. Fig. 3 is a sectional View showing the plungerdetached. Fig. 4 is a View of the bulb, shown partly in section. Fig. 5is a section through the bulb or collapsible receptacle. a plug used toclose the opening in the plunger. Fig. 7 is a section through theplunger, showing the plug in place; and Fig. 8 is a sectional view of amodified form of plunger.

In practice I provide the bulb or collapsible receptacle A, formed witha flange a, which engages around and holds the said receptacle upon acircular .or ring-shaped end b of the lever-arm B. B designates thesecond leverarm, which is pivoted to the arm B. at c, and b designates aspring fastened to the arm B at b and adapted to keep the arms normallyFig. 6 is a View of apart. A plunger 0, having a central opening 6, issecured to the end c of the arm B by means of the threaded portion 0 andis adapted to engage against the aforesaid bulb or receptacle A andcompresses same when the two arms are brought together, thereby causingany liquid contained in the said receptacle to be ejected in a finespray through very minute perforations a. Acheck-valve a is formed uponthe receptacle A and is pro vided with aflap a fastened to the inside ofthe bulb, and is adapted to open and close the said valve (L The flap ais secured to the receptacle by any suitable means along its upper edgea and is adapted to remain normally closed when internal pressure is exerted upon it.

D designates a flexible tube which passes through the opening 6 in theplunger 0 and engages and is held in the opening cl of the bulb A. Theend of the tube D is provided with a flap d, which is adapted to act asa check-valve. The said flexible tube D may be connected with anystationary or portable reservoir and alfords a means of continuouslysupplying liquid to the receptacle A.

In practice water is allowed to enter the receptacle A by means of thetube D, and the operator grasps the handles B and B, and bringing sametogether he depresses the bulb or receptacle A, thereby ejecting theliquid contained therein out through the radial openings in a finespray. The pressure of the liquid in the bulb tends to keep the valve oalways closed.

My device may also be used without the reservoir and flexible-tubeattachment, in which case the tube is removed from the opening d in thereceptacle A, and the plug E, having shoulders e, may be inserted toclose said opening. The tube is withdrawn from the opening in theplunger 0'. The plunger is removed, as shown in Fig. 8. A plug or pin Fis inserted in the said opening e and the plunger refastened to the endof the lever B. The receptacle is filled with liquid by immersing thecompressed receptacle and allowing the arms B and B to assume theirnormal condition. The receptacle expands and draws in the liquid throughthe valve 61?.

To facilitate the expansion of the bulb or receptacle A, a spiral springA may be located within said receptacle A, as shown in Fig. 5.

In Fig. 8 I show a modification wherein I providea plunger having acentral upwardlyextending portion f, which is adapted to engage in theopening e to close same. This form of plunger has no central opening andis intended for use when the tube D and its connected reservoir are notused.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In an atomizer, a collapsible receptacle for containing a liquid, aholder adapted to hold in position the said collapsible receptacle, adetachable plunger formed upon one arm of said holder and adapted toengage against said receptacle and depress same when the arms of saidholder are brought together, a flexible tubing suitably connected with areservoir and passing through an opening in the aforesaid plunger toengage in an opening upon and securely fastened within the aforesaidcollapsible receptacle and a suitable spring mounted between theaforesaid arms of holder and employed to keep the arms normally apart,substantially as described.

2. In an atomizer, a holder formed of two arms pivotally connected, aspring attached to one arm and engaging between said arms to keep themnormally apart, a collapsible receptacle having radial perforationsformed thereon and held upon said holder, an annular ledge formed uponsaid collapsible receptacle and adapted to engage around and against aring formed upon the end of one of the arms of said holder, check-valvesformed upon the said receptacle, a spiral spring mounted within saidreceptacle and adapted to facilitate the expansion of same, a detachableplunger mounted upon the end of the second arm of said holder andadapted to engage with the aforesaid receptacle to depress same, toeject the liquid contained in the collapsible receptacle through thesaid radial perforations, and a flexible tube adapted to pass through anopening formed in said plunger and connect with the interior of saidreceptacle, substantially as described.

3. In an atomizer, a holder formed of tWo arms pivotally connected andprovided with a spring engaging between said arms to keep them normallyapart, a collapsible receptacle having radial perforations formedthereon, a ledge formed upon said receptacle and adapted to engagearound and upon a ring formed upon the end of one of the arms of saidholder, check-valves formed upon the said bulb, and having an openingformed thereon adapted to receive the end of a flexible tube, adetachable plunger mounted upon the end of the second arm of said holderand adapted to engage with the aforesaid receptacle to depress same, andprovided with an opening through which a flexible tube is allowed topass and connect with the interior of thesaid bulb, and a plug adaptedto engage in the said opening in plunger and held in position by theplunger, substantially as described.

In testimony that I claim the foregoing as my invention I have signed myname, in presence of two witnesses, this 17th day of September, 1902.

MOSES GOLDMAN.
